Upper assemblies and caliber exchange kits with barrel lengths less than 16 “may only be affixed to lower receivers which (1) are not recorded as a rifle lower by the manufacturer and do not have a stock attached to the lower receiver or (2) registered with the BATFE as a short barreled rifle (SBR).

Note: Items marked as Special Order are ordered from the manufacturer. Being a manufacturer direct dealer, we are dependent on their warehouse inventory and production schedule. While most Special Order turn-around time is about 30 days, some may take a lot longer based on manufacturer availability. Your card will not be charged until the item ships.
